Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Unitary goods, refers to an integral unit formed by a group of goods or packages assembled together by one or more means to facilitate handling, transportation, stacking, and storage.

The pallet container unit refers to a whole formed by unit goods and pallets. The package assemblies are stacked on pallets, with appropriate fixings for mechanical handling and transport.

The unitized logistics refers to the logistics system which integrates the goods from the delivery place into a normalized and standardized basic unit of the goods, completes the logistics operation in each link of the supply chain through the combination and the division of the basic unit, and keeps the state of the basic unit of the goods to be delivered to the final delivery point, and the logistics form is unitized logistics.

The logistics technology refers to the theory and method of the natural science and social science adopted in the logistics activity, and the general term of facilities, equipment, devices and processes.

According to the above definition, the technical equipment and the operation method for performing the unitized logistics operation of unit cargos are called unitized logistics technology of unit cargos. Similarly, the technical equipment and the operation method for performing the unitized logistics operation of the tray packaging unit are called the unitized logistics technology of the tray packaging unit or the tray unitized logistics technology for short.

We can understand the connotations and characteristics of the two technical modes of "unitized cargo logistics technology" and "pallet container logistics technology" according to the above defined principles, distinguish their commonalities and differences, and follow and utilize these commonalities to connect or transform them with each other.

The commonality of the two technologies is that the goods or packages are assembled or combined together to form unit goods, so as to facilitate logistics operation; the unit goods are used as basic goods units, and the state of the basic goods units must be kept all the time to reach the final goods receiving point in the whole logistics process.

The difference between the two described techniques is that, by definition of terms, the unit cargo is the unit of cargo on the upper level of the container carrier. In the "unitized cargo logistics technology of pallet container units", pallets are work vehicles in which unit cargoes are fixed throughout the entire logistics process. However, in the "unitized cargo logistics technology" for unit cargo, the unit cargo can select various different operation vehicles according to business needs and operation conditions, and form a container unit of different vehicles to perform unitized cargo logistics. Namely, in the whole logistics process of unit goods, the tray can be used as an operation carrier to form a tray container unit for logistics operation; the cage car can also be used as an operation carrier to form a cage car container unit for logistics operation; the carrier can also be used as an operation carrier to form a carrier assembly unit for carrying out logistics operation. It is also possible to perform the unitizing operation on the unit goods in other forms of equipment as work vehicles or visual work vehicles, such as transfer forks, conveyor lines, gathering platforms, and flat cargo spaces. In the "unitized cargo logistics technology", the work vehicles of the unit cargo in the whole logistics process can be determined according to the work needs.

In addition, in the "unitized cargo logistics technology of unit cargo", after unit cargo of basic unit of cargo is assembled into unit cargo of larger size in a collective manner according to business needs and operation conditions, the integrated whole truck loading and unloading and transportation operation of the large-size collective unit cargo can be implemented by using a collective platform, a collective loading and unloading operation vehicle and a carriage or a container as operation vehicles. After the gathering operation link of large-specification gathering unit cargos is finished, the large-specification gathering unit cargos can be split and restored to unit cargos of the basic unit of cargos, and the next logistics operation flow is continued.

Since unit goods are goods units on the upper level of a pallet container unit, the unitized goods logistics technology requires a work technology configured to cover and engage the unitized goods logistics technology of the pallet container unit. According to the commonness of the two technical modes, in order to implement the unitized material flow operation in a logistics full-flow system with high efficiency, high quality, low cost and low emission and meet the requirements of multiple fields, multiple levels, diversification, multiple varieties and various operation scenes of the logistics operation, the logistics operation implemented by the unitized material flow technology adopting unitized goods and the unitized material flow technology adopting a tray container unit is constructed into a mode capable of realizing mutual connection or mutual conversion and coexistence.

In view of the fact that the unitized cargo flow technology of the pallet loading unit is widely adopted to perform unitized cargo flow operation, in the process of performing unit loading and unloading transportation operation of unit cargo by adopting the unitized cargo flow technology of unit cargo connected with the pallet loading unit, the pallet loading unit needs to perform pallet removing or stacking operation before a loading process, or the unit cargo needs to perform stacking and palleting operation after the unloading process. In the operation system adopting the unitization logistics technology of the unit goods to carry out the unitization loading and unloading transportation operation of the unit goods, the links of going to and going to the tray are not needed.

The unit cargo integrated loading and unloading operation vehicle or chassis provided with the flexible loading and unloading mobile platform is dynamically linked with the operation system, and the whole loading and unloading operation of the integrated unit cargo can be carried out on the vehicle or the container.

The roller bed assembly 120 is mounted on the front metro frame 11 by means of gravity pins 113 and the position height of the roller bed assembly 120 with respect to the front metro frame 11 is determined by gravity holes 1203.
